JAMES L. SIMMONS, OF BALTIMORE, MARYLAND.

Specification of Letters Patent.

Patented July 3, 1917..

Application filed October 13, 1916. Serial No. 125,364.

To all whom it may concern: Be it known that I, JAMES L. SIMMONS,

a citizen of the United States, residing at Colgate, in Baltimore city, and State of Maryland, have invented certain new and useful Improvements in Window-Cleaners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is the provision of a novel type of cleaner for the transparent pane of a wind shield, or the glass panes in the window of a car or building, or those of a boat, the said cleaner being of such construction that it can be conveniently mounted in operative position and will effectively remove the water, snow, or condensation that collects on the wind shield or window pane so as to admit of a. clear View through the wind shield or window being had at all times.

Other objects will appear and be better understood from that embodiment of my invention of which the following is a specification, reference being had to the accompanying drawings forming a part thereof, in which:

Figure 1 is a vertical elevation of a window, showing the improved cleaner associated therewith,

Fig. 2 is a vertical sectional view, taken through the window and cleaner shown in Fig. 1,

Fig. 3 is a detail perspective view of the cleaning element of the cleaner, showing the manner of connecting the same to one of the operating chains,

Fig. 4 is a detail perspective view, showing another manner in which the cleaning element can be'connected to the operating chains,

Fig. 5 is a detail perspective view of one end of the bar that connects the cleaning element, shown in Fig. 3, to the operating chains,

Fig. 6 is a perspective view of one of the links of the chain for supporting either the bar shown in Fig. 5 or the cleaning element holder,

Fig. 7 is a detail perspective view of one end of the cleaning element holder detached from operative position,

Fig. 8 is a side view of one of the bearings or one of the shafts.

In the drawings the cleaner is shown, associated with a window, which may be the window of a car or building, but it is to be understood that the cleaner can also be associated with the wind shield of a motor vehicle, for cleaning the same.

Referring in detail to the drawings, theletter A designates a window frame having a glass pane B therein. Mounted at the upper ends of the opposite sides of the window frame A is a pair of brackets which include horizontally disposed supporting arms 1, which extend outwardly from the window, the said arms having their inner ends provided with attaching flanges 2, which have connection with the sides of the window frame. Located at the lower endsof the sides of the window frame is another pair of brackets which include horizontal supporting arms 3, which have their inner ends provided with attaching flanges 4, the said attaching flanges 4 having elongated slots 5 formed therein for the reception of suitable fastening elements 6 which extend through the slots 5 and engage the sides of the frame A. By virtue of providing the attaching flanges 4 on the lowermost bracket with the elongated slots 5, said brackets can have vertical adjustment on the sides of the window frame A. The supporting arms 1 and 3 of the upper and lower pairs of brackets are provided. adjacent their outer ends, with elongated slots 7, and interposed between the supporting arms of the respective upper and lower pairs of brackets are shafts, designated, respectively, 8 and 9. The opposite ends of the shafts 8 and 9 are reduced and journaled in bearing sleeves 10,

which extend through slots 7' in the supportingarms of the upper and lower pairs of brackets. The inner ends of the bearing sleeves 10 are provided with heads 11 which engage the inner sides of the supporting arms 1 and 3 and formed on the sleeves, at points adjacent the heads 11, are shoulders 12 which slidably engage the walls of the slots 7 in the supporting arms of the brackets. The outer ends of the sleeves'lO project beyond the adjacent supporting arms of the brackets and are provided with fine threaded portions 13, which receive flange nuts 14, the said nuts 14 being adapted to be adjusted against the outer surfaces of the supporting arms and coiiperate with the heads 7 on the sleeves in tightly clamping the adjacent supporting am so as to old a manipulating crank 15. shafts 8 and 9, adjacent the opposlte ends thereof, are sprocket Wheels 16. Sprocket chains 17 connect the wheels 16 on the shaft 8 to the wheels on the shaft 9, and admit of therotation of the shaft 8 when the shaft 9 is rotated. a

Each chain 17 has two of the links thereof provided with lateral extensions 18, one of these links and the extension being shown more clearly in Fig. 6 of the drawings. Those links with the extensions 18 on one chain are located opposite the links with the extensions on the other chain, and the said extensions on. the opposed chains support elongated bars 19,- which span the space etween the chains 17. The bars 19 are provided, adjacent their opposite ends, with transverse slots 20, which open into the upperand lower sides of the bars and receive the shanks of bolts 21, which extend through openings 22 in the extensions 18. The slots 20 admit of the bars 19 having adjustment either toward or away from the chains 17 and wing nuts 23 are mounted on the upper ends of the bolts 21 and adjustable against the bars 19 and serve to hold the bars in adjusted position. The bars 19 are also provided with transverse openings 24, which open into the opposite sides of the bars 19. The openings 24 in the bars slidably receive the shanks of pins 25. The

, inner ends of the shanks 25 are enlarged, as

shown at 26, and bifurcated, and coil springs 27 embrace the shanks and are interposed between the bars 19 and the enlarged portions 26 and serve to force the pins outwardly. The inner ends of the shanks-of the pins 25 are threaded and received by nuts 28, which are adjustable against the inner sides of the bars 19 and limit the inward movement of the pins.' The pins 25 on the bars .19 support wiper holders, each of which includes a pair of superposed plates 29 and 30. ,The superposed plates 29 and 30 of the holders are received between the fingers of the bifurcated ends of the pins and are provided with ribs 31, which are formed by forcing the central portions of the plates 29 and 30 outwardly, the said ribs being received by recesses formed in the fingers of the bifurcated ends 26 of the pins 25, the recesses in the fingers being formed by forcing the central portion of the fingers outwardly, as shown at 32. The plates 29 and 30 have alined openings 33 therein, which register with openlngs in the fingers of the bifurcated ends of the pins 25, for the reception of fastening bolts 34, which serve to holdthe plates 29 and 30 against longitudinal movement and having wing nuts 34' turned thereon and adjustable against the adjacent fingers of'the bi furcated ends 26 of the pins 25. The outer edges of the plates 29 and 30 have clamped therebetween a rubber strip 35, which has its outer longitudinal edge projecting beyond the adjacent longitudinal edge of the plates 29 and 30. The strips 35 provide wipers which contact with the glass pane B when movement is imparted to the chains 17 It will be seen by referring to Fig. 2 that the wipers are located at such points that when one wiper is withdrawn from engagement with the lower end of the glass pane B, the

other wiper will be presented ,to the upper end'of the pane, so that one of the wipers will always be in position to travel down.- wardly along the pane when the chains 17 are operated. The springs 27 serve to force the pins 25 outwardly, so that the wiping strips 35 will effectively engage the glass pane B and remove any snow, water, or condensation that accumulates thereon.

If desired, the rods 19 and pins 25 can be dispensed with. and the wiper holders supported directly by. the extensions 18, as shown in Fig. 4:. When thus supported on the extensions the bolts 21 pass through registering elongated slots 36 in the plates 29 and 30 forming the holders, so as to admit of the holders having adjustment toward or away from the chains 17.

It is evident that various changes might be resorted to in the construction, form and 'arrangement'of the several parts without departing from the spirit and scope of my invention as claimed.

Having thus described I claim as new is: v

1. A window cleaner comprising a pair of sprocketchains, lateral extensions formed integral on certain of the links of the chains, bars adjustably supported by the extensions, window pane wiping elements, and adjustable and resiliently mounted holders associated with the bars and supporting the wiping elements.
